The Atari 2600 was not without software. The first mainstream videogame console sold over 30 million units on the strength of both its newness and the breadth of its game library, which numbered in the hundreds... as in, several hundreds. But the rush to publish games for the Atari 2600 was also the system's greatest weakness, as consumer confidence in the Atari 2600 -- and the entire industry -- was severely damaged by scores of high-profile bad games.
Still, many Atari 2600 games catapulted to the top of sales charts via strong word-of-mouth or smart advertising, moving over a million copies. The best-selling Atari 2600 cartridge sold approximately 7 million copies, something many modern bestsellers cannot even accomplish. This list details the top 10 Atari 2600 bestsellers, going by available market research from the early eighties. There was no NPD back then, so many of these game sales are based on internal figures recalled by figures within the industry or on the few published figures, such as two of the most high-profile flops in the history of videogames.
